plasticsepticAlltanksCom offers a full line of polyethylene septic tanks to meet the needs of the chemical, agricultural, petroleum, water, and waste water industries. Our below ground plastic septic tanks for sale come in a range of sizes and styles to fit your needs – whether you need a 1000 gallon septic tank, 500 gallon septic tank or 1500 gallon septic tank.

A poly septic tank can be easily installed with virtually no maintenance, and has a longer service life than concrete and fiberglass. Our plastic septic tanks are approved by many state and local health departments in the U.S, and have been certified by both IAPMO™ and CSA™. All products are provided with a three-year warranty from date of manufacture.

AlltanksCom Plastic Septic Tank Features:

  • Rotationally molded, one-piece seamless constructed tank
  • Molded in rib creates a superior installation below grade
  • Light weight provides easy installation; most can be transported in a pickup and handled by two people
  • Watertight lids are standard, with optional manhole extensions and lid risers available.
  • Available in both single and double compartment (2/3 – 1/3)
  • Inlets and outlets come pre-installed
  • Chemical resistant to gases (hydrogen sulfide), chemicals, and soil chemicals

Prior to installing a poly septic system, check your local health department for specific requirements that may be enforced by your county health department. Give us a call and we’ll help determine which tanks are approved in your area.
